The original 403fuzzer.py :)
Fuzz 401/403ing endpoints for bypasses
This tool performs various checks via headers, path normalization, verbs, etc. to attempt to bypass ACL's or URL validation.
It will output the response codes and length for each request, in a nicely organized, color coded way so things are reaable.
I implemented a "Smart Filter" that lets you mute responses that look the same after a certain number of times.
You can now feed it raw HTTP requests that you save to a file from Burp.
FreshRSS usage: bypassfuzzer.py -h
Simply paste the request into a file and run the script!
- It will parse and use cookies & headers from the request. - Easiest way to authenticate for your requests
python3 bypassfuzzer.py -r request.txt
Specify a URL
python3 bypassfuzzer.py -u http://example.com/test1/test2/test3/forbidden.html
Specify cookies to use in requests:
some examples:
--cookies "cookie1=blah"
-c "cookie1=blah; cookie2=blah"
Specify a method/verb and body data to send
bypassfuzzer.py -u https://example.com/forbidden -m POST -d "param1=blah¶m2=blah2"
bypassfuzzer.py -u https://example.com/forbidden -m PUT -d "param1=blah¶m2=blah2"
Specify custom headers to use with every request Maybe you need to add some kind of auth header like Authorization: bearer <token>
Specify -H "header: value" for each additional header you'd like to add:
bypassfuzzer.py -u https://example.com/forbidden -H "Some-Header: blah" -H "Authorization: Bearer 1234567"
Based on response code and length. If it sees a response 8 times or more it will automatically mute it.
Repeats are changeable in the code until I add an option to specify it in flag
NOTE: Can't be used simultaneously with -hc or -hl (yet)
# toggle smart filter on
bypassfuzzer.py -u https://example.com/forbidden --smart
Useful if you wanna proxy through Burp
bypassfuzzer.py -u https://example.com/forbidden --proxy http://127.0.0.1:8080
# skip sending headers payloads
bypassfuzzer.py -u https://example.com/forbidden -sh
bypassfuzzer.py -u https://example.com/forbidden --skip-headers
# Skip sending path normailization payloads
bypassfuzzer.py -u https://example.com/forbidden -su
bypassfuzzer.py -u https://example.com/forbidden --skip-urls
Provide comma delimited lists without spaces. Examples:
# Hide response codes
bypassfuzzer.py -u https://example.com/forbidden -hc 403,404,400
# Hide response lengths of 638
bypassfuzzer.py -u https://example.com/forbidden -hl 638
nomore403 is an innovative tool designed to help cybersecurity professionals and enthusiasts bypass HTTP 40X errors encountered during web security assessments. Unlike other solutions, nomore403 automates various techniques to seamlessly navigate past these access restrictions, offering a broad range of strategies from header manipulation to method tampering.
Before you install and run nomore403, make sure you have the following: - Go 1.15 or higher installed on your machine.
Grab the latest release for your OS from our Releases page.
If you prefer to compile the tool yourself:
git clone https://github.com/devploit/nomore403
cd nomore403
go get
go build
To edit or add new bypasses, modify the payloads directly in the payloads folder. nomore403 will automatically incorporate these changes.

Command line application that automates different ways to bypass 40X codes.
Usage:
nomore403 [flags]
Flags:
-i, --bypass-ip string Use a specified IP address or hostname for bypassing access controls. Injects this IP in headers like 'X-Forwarded-For'.
-d, --delay int Specify a delay between requests in milliseconds. Helps manage request rate (default: 0ms).
-f, --folder string Specify the folder location for payloads if not in the same directory as the executable.
-H, --header strings Add one or more custom headers to requests. Repeatable flag for multiple headers.
-h, --help help for nomore403
--http Use HTTP instead of HTTPS for requests defined in the request file.
-t, --http-method string Specify the HTTP method for the request (e.g., GET, POST). Default is 'GET'.
-m, --max-goroutines int Limit the maximum number of concurrent goroutines to manage load (default: 50). (default 50)
--no-banner Disable the display of the startup banner (default: banner shown).
-x, --proxy string Specify a proxy server for requests, e.g., 'http://server:port'.
--random-agent Enable the use of a randomly selected User-Agent.
-l, --rate-limit Halt requests upon encountering a 429 (rate limit) HTTP status code.
-r, --redirect Automatically follow redirects in responses.
--request-file string Load request configuration and flags from a specified file.
-u, --uri string Specify the target URL for the request.
-a, --user-agent string pecify a custom User-Agent string for requests (default: 'nomore403').
-v, --verbose Enable verbose output for detailed request/response logging.
